1. A multifunctional PDA, comprising:

  • a bar code recognition unit 10 for recognizing a bar code attached to a product;

    a key input unit 20 for inputting the commands of a user through keys;

    a pass card process unit 30 for allowing an unique number to be recognized when taking or getting off a subway train or bus;

    a pen type memory stick 160 for inputting the commands of the user;

    a memory stick input unit 40 for receiving the input of the memory stick 160;

    a character recognition unit 50 for converting into characters contents inputted through the memory stick input unit 40 through a translation process of analogous keyboard operations and transmitting the characters to each of applications;

    a touch screen input unit 60 for inputting the remote controller manipulating commands of a user;

    an infrared transmission unit 70 for transmitting remote controller manipulating signals to various electronic devices such as televisions, video players, audio players, etc.;

    a charge coupled device 90 for inputting images;

    a camera control unit 80 for processing the images inputted through the charge coupled device 90;

    a data storage unit 130 for storing product information corresponding to bar codes, contents inputted and processed through the pass card processing unit 30, data required to be controlled by a central processing unit, and image data inputted and processed through the key input unit 20 and the camera control unit 80;

    a central processing unit 100 for interpreting the bar code recognized by the bar code recognition unit 10, searching the data storage unit 130 for product information such as the price of the product, selling places and the like, outputting payment and delivery signals in response to the payment command inputted through the key input unit 20, controlling and storing the input and process operation of the key input unit 20 and pass card processing unit 30;

    controlling the input operation of the memory stick input unit 40 and the process operation of the character recognition unit 50, controlling and storing the input operation of the key input unit 20 and the touch screen input unit 60 and the process operation of the infrared transmission unit 70, and controlling and storing the input operation of the key input unit 20 and the process operation of the camera control unit 80;

    a data transmission/reception unit 110 for transmitting a product delivery request signal to a corresponding selling place in response to product information outputted from the central processing unit 100 and transmitting a payment request signal to one of banking facilities;

    a display 120 for displaying the operation and process results of the central processing unit 100 under the control of the central processing unit 100;

    a battery 140 for supplying power to component parts; and

    a charging terminal 150 for electrically connecting the battery 140 to an external charging apparatus.
